Error:Failed to resolve: com.google.code.gson:gson-extras:2.8.2

额外的包未在 Maven 中发布.

您可以检查这些问题:

• https://github.com/google/gson/issues/1104
• https://github.com/google/gson/issues/1123

如您所见，此包尚未发布，使用其中的类的***方法是在您的项目中包含源代码.

As you can read this package is not published and the best way to use the classes inside is just to include source-code in your project.
